Table II. 



c^ = 0'060cm., then if the velocity in absolute and relative units 

 is denoted by V and V respectively, we find 



4-61 . 10-«F= V [cm. sec.-^]; 



V can either be considered as the number of cm.^ passing each 

 cra.^ in one second or as the average linear velocity of the fluid 

 close to the membrane.
